I apologize for bad typing .... There is no good TCO tool for this, the IBM tools come close. It's not just about the io, the chip speed, the ability to push pull,to offload io onto other chips. It's about all things. No x86 platform has the scads of shared cache at multiple levels of the chip that z does. You want to bog down X do context switching. You think your X can handle the io well remember to add more X cores to do that io on my eckd io doesn't count.
Show me an X system that you have added 3800 Oracle Dbs to, without growing floor space, power consumption or network switch connections. I have a Z environment it's been done to. Show me an X system w 35000 + wwpn /lun zone pairs that supports swapping the server hw without rezoning. I can go on but I hate typing w one finger on my phone.
